Ever been frustrated by a screw that just won’t stay put? You’re not alone. I’ve been there, and many expert woodworkers. The culprit? Stripped wood screw holes. Luckily, I’ve discovered some nifty ways to fix them. If you want learn more, keep reading!
Fixing Stripped Wood Screw Holes: 6 Methods
Here are the methods to fix stripped screw holes for your DIY projects.
Method #1: Use a Longer or Thicker Gauge Screw
The easiest and simplest way to fix a stripped screw hole with fewer threads is using a longer screw or a thicker gauge screw with new threads.
Replacing loose screws can solve your problem. The new screw should have the same type of threads as the old screw to fix a stripped screw hole.
If the previous screw occupied the whole workpiece, the bigger screw with more screw threads would not be a quick fix. The extra threads from the longer screw will provide a good grip.
Method #2: Use Toothpicks, Matchsticks, or Chopsticks
What You Need
- Wooden toothpicks, wooden matchsticks, or hardwood dowels
- Wood glue
- Hammer
- Screwdriver
Step-by-step Process
- Get a few pieces of toothpicks to make the hole smaller.
- Squeeze a few drops of glue that you can buy at hardware stores or home centers on the exposed part of the toothpicks.
- Spread the glue using your fingers or cotton swabs.
- Stick the toothpicks into the stripped hole and lightly beat the end.
- Snap off the excess parts of the toothpicks.
- Let the wood glue dry for at least an hour
- Once dry, drive the stripped-out screw back into the hole.
Method #3: Fill the Hole with Wood Strips and Re-Drive the Screw
To fix a stripped screw hole, another solution is to insert small strips of the same type of wood as the original and then re-drive the screw. You can create these strips by obtaining shavings or thin pieces from a similar type of wood.
Dip the tips of the fresh wood into the glue and insert them into the stripped screw hole. Lightly tap it until the hole is filled. Let the glue set for a few hours. Once dry, you may trim the excess filler using a chisel or knife.
Method #4: Use Hardwood Plugs or Dowels
If any of the padding techniques didn’t work, it is time to move to a higher level of fixing stripped holes.
What You Need
- Dowel(s) (⅜”) from a hardware store
- Pilot bit
- Large drill bit (⅜ “)
- Wood glue
- Hammer
- Coping saw
- Screwdriver
Step-by-step Process
- Using a drill driver or screwdriver, remove the old screw.
- Make the pilot hole larger using a large drill bit to create more space around the lag screw or hinge screws.
- Insert the dowel or the hardwood plug into the hole.
- Mark the depth of the hole and cut the dowel to size using a saw.
- Cover the dowel with glue and put it back in the hole.
- Wait for at least 20 minutes for the dowel to dry.
- If you used a hardwood dowel, you need to make a pilot hole before putting the object back together.
Method #5: Use Plastic Anchors or Plastic Wall Plugs
Another method of fixing stripped screw holes is by using plastic anchors or wall plugs.
- Choose the right size of plastic anchor or plug. It should fit into the hole and be at least the same length as the screw.
- Insert the anchor or plug it into the stripped screw hole.
- Drive the screw into the plastic anchors and you are all set.
Method #6: Use Auto Body Filler
Auto body filler can also be used in fixing splits that will not thread. The resin [1] will do the trick in this method.
What You Need
- Large drill bit
- Auto body filler and hardener
- Power drill
- Mixing board
- Lubricant
- Utility knife or chisel
Step-by-step Process
- Make a larger hole using a power drill. Pull the trigger to make the hole.
- Mix the body filler and hardener on the board.
- Fill the hole with more filler mixture with lightweight applications.
- Spray the screw with the lubricant to act as a release agent.
- Thread the lug screw in the hole.
- Wait for at least 5 minutes for the padding to dry.
- Remove the spare mixture using a utility knife on top of the bolt.
- Remove the screw by unthreading it using your hand until the screws loosen.
- Let the resin be fully cured for a moment before installing the new screw.
Why Do Wood Screw Holes Strip?
There are several possible reasons, some of which are:
- Installing and uninstalling screws multiple times
- Overtightening the original screw
- Exerting too much force on a screw
- Installing the wrong wood screws
FAQ
How do you fix a screw that won't tighten?
To fix a screw that won’t tighten, you must use the right tools. Using a larger screw can make all the difference. If the screw doesn’t tighten no matter how much you turn it, you may need to use more shim or a new hole.
What is the best wood filler for screw holes?
The best wood filler for screw holes should be the same species of wood as the original holes. It will prevent further damage to the hole and you will be sure it will look good. You may use a simple filler such as a toothpick, resin, or plugs.
